Parking in the centre of Chambry (a few kilometres north of Meaux), around a small triangular square where the war memorial stands (a small obelisk topped with a cockerel).
No markings
(S/E) Facing the war memorial, head east-northeast on the left side of the square, along Rue d'Ortheuil. Join the D140 and turn left towards Barcy.
(1) Shortly before the Chambry exit sign, turn left onto a wide, stabilised path and walk along the cemetery on your right. The path runs almost constantly north-west: stay on this main path and ignore any secondary paths on either side. A short asphalt section and a small bridge take you over the TGV Est railway tracks. You will reach the Notre-Dame de la Marne monument.
(2) Follow the D97 road to the left towards Barcy. At the stop sign, cross the perpendicular road and enter Barcy, where you will see the church tower. At the end of the church, turn left into Ruelle du Curé, with the town hall on your left and the church on your right. You will reach Place Sainte-Geneviève.
(3) Continue in the same direction (west-southwest) on a larger road coming from the right. Cross a road at the edge of the village, walk alongside a sports field and you will reach the Fontaine Sainte-Geneviève fountain, located in a grove of poplar trees visible from afar.
(4) Turn right (north-west) onto a very small road. Cross a stream and walk slightly uphill to a crossroads where you can see the hamlet of Saint-Gobert on your right.
(5) Take the path on the left, which quickly becomes grassy. After a "no vehicles" sign, the path veers to the left and is bordered by a hedge on the left-hand side.
(6) At the intersection, turn left onto a grassy path and follow a stream on your right. Pass two road signs and turn right (south). After about 200 m, the path turns right again (south-west), widens and becomes stony. Ignore a path on the left, walk past the Croisette farm on your right and you will come to a junction with the N330 in Monthyon.
(7) Cross the road at the traffic lights and follow the D97 opposite towards Juilly/Iverny. Stay on the main road lined with houses, keep heading south-west and ignore all the side streets.
Red and white markings
(8) At the end of the residential area, turn left onto Chemin de Penchard and follow theGR®®1. Go around a group of buildings (palisade topped with barbed wire) on the left. At the high-voltage power line, ignore a fork on the left and continue south-east.
(9) Pass under the TGV Est bridge, cross a stream and pass a metal cross. The path climbs gently to enter the Bois de Penchard (information board at the entrance).
No markings
(10) A few dozen metres after entering the woods, leave theGR®® and continue straight ahead (south-east) along the Sentier de la Brigade Marocaine, marked by an arrow pointing to "7 Stèle Hugot-Derville" accompanied by the silhouette of a Moroccan soldier from 1914. Climb up alongside a fence on your left below. Reach a flat area and descend, continuing south-east.
Red and white markings
(11) At a fork (signs 7 and 8 on the Sentier de la Brigade Marocaine), rejoin theGR®® and continue straight ahead, downhill. After a few metres, at the corner of the wire fence on the left, take a path that climbs to the left (be careful, theGR®® marker is not easy to spot). The path climbs and descends slightly through the undergrowth and then reaches a more open area near some houses. Follow another fence, this time on your right, until you reach a crossroads.
(12) Go down the street on the right and pass the cemetery and church of Penchard. You will come to a crossroads near the town hall.
No markings
(13) Follow the D140 to the left towards Chambry. After about 20 metres, leave theGR®®1on your right and stay on the main road (D140), preferably on the left-hand side. The road soon turns right, heading east-northeast. Cross the N330 on a bridge, staying outside the safety barrier. Continue on the D140 for another 250 metres or so.
(14) Take a very small road on the left that leads to Château d'Automne. This road, which has very little traffic, first takes you back the way you came and then runs alongside the N330 at a higher level (this is safe as there is a large embankment between the two).
(15) After walking about 900 metres along the small road, before it becomes lined with trees on both sides, take a grassy path on the right. When you reach Château d'Automne, at the edge of the woods, turn right (east-northeast) at a 90° angle and enter the woods. Ignore a path on the right (elevation 125) and continue northeast. Exit the woods and continue on a wide grassy path between the fields.
(16) Come out onto a small road and follow it to the right. Cross the D38 and take the path opposite, which quickly veers to the right and then climbs slightly.
(17) At the T-junction, turn left and head towards a small group of trees. The path descends and then runs alongside the trees (on the left) until it reaches a perpendicular path. Make a zigzag left-right turn and head towards the houses.
(18) At the entrance to Chambry, follow Rue des Prés on the right. Pass in front of the school and you will soon reach the starting point (S/E).
